Expression: _BLOCK_TYPE_IS_VALID(pHead->nBlockUse) Error

Question

This error occurs during run time, and I\'m not sure what\'s causing it - the code looks correct to me.

#include 
#include 

using

Your problem is here:

void Event::set(Room r, const std::string& name) {
    d_room = &r;
    d_name = name;
}

The &r takes the address of an object whose lifetime ends when the function returns, resulting in undefined behaviour when you later try to access it.

If you want to use pointers, you need to allocate them dynamically:

void Event::set(Room* r, const std::string& name) {
    d_room = r;
    d_name = name;
}

// ...
for (int i = 0; i < noLect; ++i) {
    Room* r = new Room;
    r->d_noSeat = i + 1;
    r->d_hasProjector != r.d_hasProjector;
    lectures[i].set(r, "CSI2372");
    lectures[i].print();
}
// ...

But it doesn't look like you need pointers here, you should be able to have

Room d_room;

in the Event class.
